Netflix has just added an incredibly unsettling new thriller series

Based on a shocking true story, the show features one of the best TV performances in years.

Written by, created by and starring Scottish comedian Richard Gadd, the show centres around Donny - an aspiring Scottish stand-up who moved to London to pursue his career dream.

Now in his late 20s and working a dead-end job in a pub though, he feels like a failure.

So, when an older female patron at his bar named Martha (Jessica Gunning) laughs at his jokes and shows an interest in him, he is at first pleased with the attention - endeavouring to get more positive reactions out of her.

It turns out, however, the seemingly friendly Martha has a history of stalking and winds up forming a dangerous obsession with Donny.

Adapted from Gadd's hit one-man play of the same name and based on true events that happened to the writer and performer, Baby Reindeer is sure to earn comparisons to Phoebe Waller-Bridge's Fleabag thanks to its series narration and its use of black comedy to explore serious themes.

Bear in mind though that the new Netflix show is much darker and more unsettling in tone than Fleabag because of the warped relationship at its centre and how it forces Donny to face his own personal demons, as well as Weronika Tofilska's horror-inflected direction.

It is also worth noting that Jessica Gunning gives one of the best TV performances in years in the series, managing to be sweet and sympathetic one moment and utterly terrifying the next.

All seven episodes of Baby Reindeer are streaming on Netflix right now.
